Less than .1% of the energy in a food chain generally makes it from the sun to consumers
Elena-2011 [213]

This statement is true.

Reason:

Plants are capable of storing energy from the sun and with the help of that they produce their own food. And this energy is transformed to the animals as well as human being when they consume the food which was grown on the plants. But when they consume it they are only able to get 10% of the energy and the last consumers are able to get only about 1% of the energy.
